📋 Resumen Ejecutivo

Este documento consolida todo el trabajo realizado en los sprints v0.1.1 y v0.1.2 del proyecto AbletonMCP-AI. Incluye:

• Todas las tareas completadas
• Archivos modificados con líneas específicas
• Código de cambios importantes
• Estado de validación
• Issues conocidos
• Próximos pasos recomendados

Hallazgo clave: El 80% del código estaba implementado pero sin validación runtime. El sprint v0.1.2 se enfocó en verificar la realidad vs. la documentación histórica.

🔧 Cambios Detallados

1. clear_all_tracks - FIXED ✅

Problema original: Error blando "Couldn't delete track" al limpiar + timeout en sesiones grandes

Solución aplicada:

# abletonmcp_init.py:529
# CAMBIO: Extender timeout para clear_all_tracks
if command_type in ("generate_track", "clear_all_tracks"):
    timeout_seconds = 180.0  # Era solo 10s
else:
    timeout_seconds = 10.0

# abletonmcp_init.py:2664-2698
# _clear_all_tracks method - Lógica completa

def _clear_all_tracks(self, params):
    """Clear all tracks and leave exactly one empty track."""
    tracks_deleted = 0
    
    # Delete tracks from the end to avoid index shifting
    while len(self._song.tracks) > 1:
        track_idx = len(self._song.tracks) - 1
        self._song.delete_track(track_idx)
        tracks_deleted += 1
    
    # Clear the remaining track (can't delete last one)
    if len(self._song.tracks) == 1:
        track = self._song.tracks[0]
        
        # Clear all clip slots
        if hasattr(track, 'clip_slots'):
            for slot in track.clip_slots:
                if slot.has_clip:
                    slot.delete_clip()
        
        # Remove all devices
        if hasattr(track, 'devices'):
            while len(track.devices) > 0:
                track.delete_device(0)
        
        # Reset name and color
        track.name = "1-MIDI"
        if hasattr(track, 'color'):
            track.color = 0
    
    return {
        "status": "success",
        "tracks_deleted": tracks_deleted,
        "message": f"Cleared {tracks_deleted} tracks, left 1 empty track"
    }

Validación:

• ✅ 3 limpiezas consecutivas sin crash
• ✅ Sesiones de 16+ tracks limpiadas correctamente
• ✅ No más timeout en sesiones grandes
• ✅ get_session_info devuelve consistentemente 1 track

2. Z.ai Backoff/Retry/Cache - IMPLEMENTADO ✅

Archivo: AbletonMCP_AI/AbletonMCP_AI/MCP_Server/zai_judges.py

Configuración:

# zai_judges.py:29-34
CACHE_TTL_SECONDS = 300  # 5 minutos
MAX_RETRIES = 3
BACKOFF_DELAYS = [1.0, 2.0, 4.0]  # Exponencial

Cache con SHA256:

# zai_judges.py:37-53
def _generate_cache_key(self, system_prompt: str, payload: Dict) -> str:
    """Generate cache key from prompt and payload."""
    cache_data = {
        "prompt_prefix": system_prompt[:200],
        "genre": payload.get("genre", ""),
        "style": payload.get("style", ""),
        "bpm": payload.get("bpm", 0),
        "key": payload.get("key", ""),
        "judge_role": payload.get("judge_role", ""),
        "candidates": [c.get("id", "") for c in payload.get("candidates", [])[:4]]
    }
    json_str = json.dumps(cache_data, sort_keys=True)
    return hashlib.sha256(json_str.encode()).hexdigest()

Retry loop con backoff:

# zai_judges.py:155-205
def _call(self, system_prompt: str, payload: Dict) -> Dict:
    """Call Z.ai API with retry and cache."""
    cache_key = self._generate_cache_key(system_prompt, payload)

        return cached_result
    
    # Try API with retries
    for attempt in range(1, MAX_RETRIES + 1):
        try:
            response = self._make_api_call(system_prompt, payload)
            self._set_cached_result(cache_key, response)
            return response
            
        except HTTPError as e:
            if e.code == 429:
                if attempt < MAX_RETRIES:
                    delay = BACKOFF_DELAYS[attempt - 1]
                    logger.warning(f"Judge API 429 on attempt {attempt}/{MAX_RETRIES}, retrying in {delay}s...")
                    time.sleep(delay)
                    continue
            raise
        except (URLError, TimeoutError) as e:
            if attempt < MAX_RETRIES:
                delay = BACKOFF_DELAYS[attempt - 1]
                logger.warning(f"Judge API error on attempt {attempt}: {e}, retrying...")
                time.sleep(delay)
                continue
            raise
    
    return {}  # Fallback empty

Fallback heurístico:

# zai_judges.py:225-242
def judge_palette_candidates(self, candidates: List[Dict], context: Dict) -> Dict:
    """Judge palette candidates with API or heuristic fallback."""
    try:
        result = self._call(system_prompt, payload)
        if not result:
            # API failed - use heuristic fallback
            logger.warning("Z.ai judges failed, using heuristic fallback")
            return {
                "mode": "heuristic_fallback",
                "selected": candidates[0] if candidates else None,
                "directives": {
                    "rhythm_density": "moderate",
                    "bass_motion": "rolling",
                    "arrangement_emphasis": "balanced",
                    "vocal_strategy": "sparse"
                }
            }
        return result
    except Exception as e:
        logger.error(f"Judge panel failed: {e}")
        return {"mode": "error", "selected": candidates[0] if candidates else None}

Estado: Implementado, necesita validación contra API real con 429

    # Different pack - penalty
    return 0.4, "fallback", "Cross-pack selection"

Section-aware selection (NUEVO v0.1.2):

            'bpm': self.bpm,
            'kick_positions': self.kick_positions,
            # ... etc
        }

Detección de transientes:

# audio_analyzer.py:180-220
def _detect_transients_librosa(self, audio: np.ndarray, sr: int) -> np.ndarray:
    """Detect transient positions using librosa onset detection."""
    # Onset envelope
    onset_env = librosa.onset.onset_strength(
        y=audio, 
        sr=sr,
        hop_length=512
    )
    
    # Peak picking
    onset_frames = librosa.util.peak_pick(
        onset_env,
        pre_max=3,
        post_max=3,
        pre_avg=3,
        post_avg=3,
        delta=0.5,
        wait=3
    )
    
    # Convert to timestamps
    onset_times = librosa.frames_to_time(onset_frames, sr=sr, hop_length=512)
    
    # Filter by energy (RMS)
    onset_times = self._filter_by_energy(audio, sr, onset_times)
    
    return onset_times

Resultados:

• v0.1.1: 11 templates (solo drumloops/*.wav)
• v0.1.2: 16 templates (76 archivos escaneados recursivamente)
• Cache: ~/.abletonmcp_ai/dembow_groove_templates.json

Estado: Implementado y expandido, probado con librería real

⚠️ ISSUE CRÍTICO ENCONTRADO:

Problema: El servidor MCP se bloquea completamente durante la generación

Síntomas:

1. Job se encola correctamente (status: "queued")
2. Job cambia a "running"
3. Servidor deja de responder a cualquier comando MCP
4. get_generation_job_status timeout
5. Después de 10+ minutos, servidor crashea

Logs de error:

MCP error -32001: Request timed out
Connection closed
[WinError 10054] An existing connection was forcibly closed

Causa root: ThreadPoolExecutor no libera el GIL de Python durante la generación, bloqueando todo el servidor MCP.

Posibles soluciones:

1. Usar multiprocessing.Process en vez de ThreadPoolExecutor
2. Añadir asyncio con run_in_executor y checkpoints
3. Separar el job runner en proceso independiente con queue
4. Usar fastapi o similar para endpoint de status separado

6. Smoke Test - IMPLEMENTADO ⚠️ CON ISSUE

Archivo: temp\smoke_test_async.py (547 líneas)

Estructura:

class MCPServerClient:
    """Client to invoke MCP tools directly from server.py."""
    
    def __init__(self):
        self.server_module = self._load_server()
    
    def _load_server(self):
        spec = importlib.util.spec_from_file_location(
            "server", 
            r"C:\ProgramData\Ableton\Live 12 Suite\Resources\MIDI Remote Scripts\AbletonMCP_AI\AbletonMCP_AI\MCP_Server\server.py"
        )
        server = importlib.util.module_from_spec(spec)
        spec.loader.exec_module(server)
        return server
    
    async def generate_song_async(self, **kwargs):
        return await self.server_module.generate_song_async(**kwargs)
    
    async def get_generation_job_status(self, job_id):
        return await self.server_module.get_generation_job_status(job_id)

class SmokeTest:
    """End-to-end smoke test for async generation."""
    
    async def run(self):
        # 1. Test connection
        # 2. Launch async job
        # 3. Poll status
        # 4. Verify tracks
        # 5. Check manifest
        pass

Uso:

# Test básico
python temp\smoke_test_async.py

# Con opciones
python temp\smoke_test_async.py --use-track --genre tech-house --poll-interval 2

# Con reporte JSON
python temp\smoke_test_async.py --save-report report.json --json

⚠️ Issue encontrado: El smoke test carga server.py mediante importlib.util.spec_from_file_location(), lo que crea una instancia de módulo separada. Esto significa que el diccionario global _generation_jobs no es compartido entre la llamada de submit y la de status check.

Fix necesario: Usar una sola instancia del cliente MCP o usar el socket directo de Live para status.

⚠️ Issues Conocidos

Críticos

1. Server MCP se bloquea durante generación async

   • Impacto: Clientes no pueden consultar status, timeout
   • Causa: ThreadPoolExecutor mantiene GIL
   • Workaround: Ninguno, necesita fix
   • Prioridad: ALTA

2. Smoke test module isolation

   • Impacto: "Job not found" en primer poll
   • Causa: _generation_jobs no compartido entre instancias
   • Fix: Usar socket directo o singleton
   • Prioridad: MEDIA

3. BPM detection en loops

   • Impacto: Todos los templates muestran 95.0 BPM
   • Causa: librosa clasifica loops como one-shots
   • Fix: Mejorar algoritmo o usar metadata
   • Prioridad: BAJA

Importantes

4. clear_all_tracks error blando

   • Impacto: Mensaje "Couldn't delete track" al final (aunque funciona)
   • Estado: Fix de timeout aplicado, error puede persistir en logs
   • Prioridad: BAJA

5. Async generation toma 10+ minutos

   • Impacto: Tests timeout antes de completar
   • Causa: Generación heavy + server blocking
   • Workaround: Necesita fix del blocking
   • Prioridad: ALTA

🎯 Próximos Pasos Recomendados

URGENTE - Fix Server Blocking

Opción A: Multiprocessing (Recomendado)

# En lugar de ThreadPoolExecutor
from multiprocessing import Process, Queue

def _submit_generation_job(job_type, params):
    job_id = generate_uuid()
    queue = Queue()
    process = Process(
        target=_run_generation_in_process,
        args=(job_id, job_type, params, queue)
    )
    process.start()
    
    # Main process sigue libre para responder MCP
    return job_id

Opción B: Asyncio con checkpoints

async def _generate_with_checkpoints(params):
    for section in ['intro', 'build', 'drop', 'break', 'outro']:
        await generate_section(section)
        await asyncio.sleep(0.1)  # Yield control

Opción C: Servidor de jobs separado

• Crear job_runner.py como proceso independiente
• Comunicación via socket o archivo
• MCP server solo orquesta, no genera

Media Prioridad

6. Validar same-pack selection

   • Generar track y inspeccionar logs
   • Verificar fill_fx/snare_roll vienen de pack principal

7. Validar Z.ai retry

   • Probar contra API real
   • Forzar 429 si es posible (rate limiting)

8. Fix smoke test

   • Usar socket directo de Live (127.0.0.1:9877)
   • O mantener singleton del server module

Baja Prioridad

9. Mejorar BPM detection

   • Usar tempo detection más robusto
   • O parsear BPM del filename

10. Documentar groove templates

    • Listar todos los templates extraídos
    • Documentar qué loops son mejores

📝 Notas para Codex

1. No confíes ciegamente en docs históricos: Siempre verificar con código real primero
2. Separar implementación de validación: El código puede estar listo pero sin probar en vivo
3. Server blocking es el issue más crítico: Arreglar esto primero antes de más features
4. Usar PowerShell en Windows: No bash, rutas absolutas Windows
5. Validar con runtime: get_session_info, get_tracks, logs de Ableton
6. El puerto 9877 escucha: Pero eso no significa que todo funcione

Reality Check (Added 2026-03-30)

Claims vs Reality

Claim	Reality	Status
"Código implementado 100%"	Code exists but not all wired to real flow	PARTIAL (85% wired)
Section-aware selection works	Code exists in sample_selector.py but not called from server.py during generation	NOT WIRED
Joint scoring (drum kit coherence)	JOINT_SCORING_GROUPS defined but selections not recorded, joint scoring not applied	NOT WIRED
record_section_selection	Method exists but never called	DEAD CODE
section_context tracking	SECTION_ROLE_PROFILES exists but section context never set	NOT WIRED
Async jobs work	Infrastructure exists but server blocks during generation	ISSUE FOUND
Same-pack strict selection	Code ready but not validated in real generation	UNVALIDATED
Z.ai retry/cache	Implemented but not tested against real 429s	UNVALIDATED
Groove extractor	Implemented and tested with real library	✅ WORKS
clear_all_tracks	Implemented and validated in Live	✅ WORKS

What's Actually True

• ✅ clear_all_tracks: Implemented and validated in Live 3/3 times
• ✅ Z.ai retry/cache infrastructure: Implemented with exponential backoff
• ✅ Groove extractor: 16 templates extracted from real library
• ✅ Async job queuing: Jobs queue correctly
• ⚠️ Section-aware selection: Code exists but DEAD (not wired to server.py flow)
• ⚠️ Joint scoring: Groups defined but no selection recording → no joint scoring
• ⚠️ Async status polling: Infrastructure ready but server blocking prevents status checks
• ❌ Async completion: Jobs start but server blocks, causing timeouts

What Needs Wiring

1. section_context needs to be set from server.py during generation

   • Currently SECTION_ROLE_PROFILES exists but never used
   • Generation flow doesn't know which section it's in

2. record_section_selection needs to be called after each selection

   • Method exists in sample_selector.py
   • Never called from generation flow
   • Required for joint scoring to work

3. joint_scoring needs selections to be recorded first

   • JOINT_SCORING_GROUPS and FOLDER_COMPATIBILITY_BONUS defined
   • Can't apply joint scoring without recorded selections

4. Section-aware filtering needs to be integrated into selection flow

   • SECTION_ROLE_PROFILES defines primary/secondary/avoid per section
   • Not used in actual select_samples() call chain

Honest Assessment

What works: Infrastructure, extraction, caching, clearing tracks, compiling
What exists but is dead: Section-aware selection, joint scoring, same-pack strict enforcement
What has issues: Async blocking, smoke test module isolation
What's unvalidated: Same-pack selection, Z.ai 429 handling

Bottom line: ~40% of features are runtime validated, ~45% exist but aren't wired, ~15% needs fixing.
